Freescale Semiconductor

Technical Data

Low Power CMOS Broadband Tuner

Freescale Semiconductor’s MC44S803 is a 3.3 Volt, low power, high

performance, single-chip CMOS, broadband tuner. This chip offers a

cost-effective, low-power solution for high-performance analog and digital TV

market. This highly integrated third generation silicon tuner covers a 48 MHz to

1 GHz RF input and converts to a 30 MHz to 60 MHz IF frequency. The 861 MHz

to 1 GHz frequency range is supported with reduced performance.

MC44S803

The single-chip broadband tuner uses a double-conversion architecture,

which eliminates tracking filters and their manually aligned coils. Two IF outputs

are provided to support systems with multiple demodulators (e.g. one digital

demodulator and one analog TV demodulator).

LOW POWER CMOS

BROADBAND TUNER

The MC44S803 is designed to meet all Data Over Cable Service Interface

Specification (DOCSIS), ATSC specifications for 8VSB, 64- and 256-Quadrature

Amplitude Modulation (QAM) as well as the NorDig Unified 1.0.3 specifications

for Coded Orthogonal Frequency Division Multiplexing (COFDM) for DVB-T.

The device is available in a Pb-free 64-pin quad leadless package (QFN).

Features

•

Low power consumption (746 mW typical)

Single 3.3 V supply operation

Programmable power down mode with fast start-up

Variable-gain Low-Noise Amplifier (LNA) with 40 dB gain control range

Ability to switch between two external analog control voltages for LNA

Two fully integrated frequency synthesizers
